immersed in the said reservoir said drum Be it known that I, AsnJonN SONSTHAGEN,

a subject of the Kingof Norway, residing in Leytonstone, Essex, England, have invented certain new and useful Improvements in' Machines for Coating Sweetmeats, of which the followmg 1s a specification.

This invention relates to machines for coatingv sweetmeats and it refers to machines of the kind in which cores or centres of suitablerm'aterial are coated. or covered by passing' them through a stream of the coating material. I

In machines of the type referred to the coating material, chocolate for eXample,'1s,

discharged from a hopper or receptacle into a trough-like receptacle having a longitudinalopening for the escape of theimaterial. The present invention has for its primary obj ect certain improvements designed to pre ventthe clogging or choking of the discharge aperture. j j

The invention further provides certain improvements in the construction and arrangementof the trough'hdapted to permit its readyfrenioval and replacement and in the hopper supplying the material tothcsaid trough.

In order that the invention may be the better understood drawings are appended in which i i Fig; 1 isan end view of a trough embodying, the-present invention,

Fig. 2 is an elevation of onexofthe end brackets for supporting the trough, Fig. 3. is an elevation of a bracket for supporting;

the other end of the trough. v

Fig.4 is a front view of the trough with certain parts omitted.)

Fig. 5 is a plan of the trough. I Fig. 6 is "a cross-section of the trough. .Fig. 7 is a sectional View to a larger scale showing the application of the invention to an existing machine,' and Fight; is a transversesection to a smaller scale than that of Fig. plied to the machine. I 1 "Referring to the accompanying drawings. 1 indicates the trough into which the liquid chocolate is delivered and from which "it falls in a stream upong'the cores; which are carried" by a belt or conveyor arranged and operated in the manner usual to machines of this type.

The chocolate in the form of machine illustrated is conveyed from themain reser- 7 of the trough ap-- during its rotationpas'sing under the inclined plate '3 ,where-by the chocolate is scraped from the periphery of'said drum and fed onto the inner surface of the'body i.

Disposed at the uppermost pointof the periphery of the body 4 and'eng'raging the inner surfaceof said body' is a second scraper skilled in the art to render further descrips tion unnecessary. The trough -1 is provided at tll'bOttOlll with a longitudinal opening w, formed as] will be hereafter described, in which is disposed a bar 7 of substantially inverted Y section, the vertical portion 7 of which freelyenters, said slot in a manner such that there is left upon each side thereof ample clearance for the passage-of the chocolate.

It may here be stated that whilst chocolate is referred to as the coating material it is to be understood that other material may be used. o

The bar 7 is supported at each end by means of arm '8, 9, pivoted respectively to the wall or frame of the machine and the bar 10. The, arms 8, 9, are each provided with a projection 11 having a bevelledface, each of which projections bear upon the face of ratchet or like wheels :12 whereby when the wheels are rotated'avertical reciprocal motion is imparted to the bars effectually preventingany clogging of the discharge apertureor trough 1. The motion of wheels 12 may be secured bymounting them upon,

a shaft 13 supported at its ends respectively by the/bar 10 and the frame or wall ofthe machine. The shaft passes through the wall of the machine and has at its end a chain wheel 14 around which passes a chain I 15 passing'over a second chain wheel 16 mounted on a shaft 16 supported by brackets 16" of the top of the machine.

It will be noted that the bar 7 constitutes length of the slot or discharge opening and is movable laterally thereof for preventing clogging of the material during flow through the slot.

Motion is imparted to the shaft 16 by a chain wheel 17 upon shaft 16 around which passes a chain 18 operated by a chain wheel upon the shaft or spindle of body l.

In order that the air may escape from the underside of the inverted Y-shaiped bar 7 and so avoid being mixed with the chocolate a perforation, indicated by 10 may be formed in the end of the bar as shown more clearly in Fig. (3.

Preferably provision is made whereby the width of the slot or opening w of trough 1 may be varied within certain limits. To this end the parts or members of the trough separated by the slot to are pivotally mounted, that indicated by 1 being mounted by means of pivots at its upper end upon its end walls a and Z) and in order that the said part may be adjusted and secured after adjustment there is pivotally connected to it a link 19, Figs. 1 and 6, attached to a second link 20 pivoted upon the outer end of the trough. The connection of the two links is eliiected by means of a stud passing through the two links and through a radial slot in the bracket, a lock nut being provided upon the outer end of the stud. 23 indicates a. handle for operating the links.

The opposite side or part 1 of the trough has secured to it plates 2st 1 and (3 said part itself being pivotally mounted at its upper ends in the supporting brackets. The plates 24: 1 extend upwards beyond the upper edge of part 1 and have pivotally connected to them one end of a stud or screw 25 the end of which passes through a nut 26.

The nut 26 is recessed to engage the inner edges of a slot formed in suitably slotted extensions on the brackets a and Z). By turning the nut in one or other direction the part 1 may be correspondingly tilted and the width of the opening for bar 7 varied as desired. As both parts of the trough are movable it is possible to so adjust them that the space on both sides of the bar are equal.

Distance or spacing means 2-7, Fig. 5, is provided for the end walls a, b, of the trough members, the distance between the inner faces of the said walls being such that:

whilst the parts 1 and 1 of the trough may move freely. there is not a sutiieient clearance between the ends of the trough members and the inner faces of the walls to permit the chocolate to escape at these points.

Vhilst the trough may be innnovably mounted in the machine it is preferred to so mount it that it may be readily removed when so desired for cleaning or other purposes.

31, of inverted ll-shaped outline formed upon the outer surfaces of the end members F of the trough.

The third triangular projection 30 of the brackets engage the inclined surface 33 of the strengthening flange 3i upon the outer surface of the end wall of the trough.

Obviously the construction, arrangcn'icnt and method of operation of the bar 7 may be varied as desired and instead of having only vertical reciprocal motion said bar may be arranged to reciprocate transversely of the opening in which it mounted, or have both transverse and vertical motion in said opening.

Provision may be made whereby the distance from the trough to the conveyor may be varied as desired.

Havin thus described my invention, it
